Bureau of Indian Standards

BIS, is the national code laying body for Electrical Equipment in Potentially Hazardous Locations. They are instrumental in setting the guidelines / standards in the areas of Equipment construction & testing, Area Classification, selection, installation and maintenance of Ex equipment. Karandikar Laboratories Pvt. Ltd. is India's first private sector laboratory which is recognized by the BIS for issuing test reports of product testing for BIS approval. BIS approved Ex testing scope of Karandikar Laboratories Pvt. Ltd. is listed in table below. On recommendation of the Electro technical Division Council, BIS has aligned IS Standards with IEC standards.

KLPL- A Partner Laboratory
of Bureau of Indian Standards

Although, this BIS scheme itself is voluntary in nature, The Petroleum Explosive Safety Organisation, PESO & Director General Mines Safety, DGMS, has enforced a mandatory requirement for Indian Manufacturers towards BIS certification (as per IS/IEC 60079~0:2007 IS/IEC 60079.1:2007) on products (conforming to flameproof Ex "d" protection concept)

Petroleum & Explosive Safety Organisation, CCoE

The objective of PESO is to regulate and monitor the manufacture, import, export, transport, possession, sale and use of explosives, petroleum products and compressed gases as envisaged under the Explosives Act 1884 and Petroleum Act 1934.

PESO is currently involved in regulation of over 2,56,000 premises all over India. The approval of chief controller of explosive CCoE is mandatory for all electrical equipment installed in potentially explosive atmospheres.

  • Rule 106 of Petroleum Rules prescribes that all equipment operating on electrical energy are required to be approved by Chief Controller of Explosives if they find application in hazardous areas falling within the purview of Petroleum Rules, 2002. The approval of electrical equipment is therefore limited to only such areas falling within the jurisdiction of Petroleum & Explosives Safety Organisation
  • Chief Controller of Explosives permits use of flameproof, intrinsic safety and encapsulated type protected equipment for use in zone 1 hazardous areas. Non sparking and increased safety type equipment are permitted in zone 2 hazardous areas.

The test certificate issued by Karandikar laboratories enables a manufacturer to obtain approval from CCoE.

PESO Approval of Karandikar Laboratory

PESO Equipment
Approval Policy

We enable the manufacturer to understand-

  • Technical details of the equipment including engineering drawings
  • Understanding the requirements of the standards
  • Evolving a test program based on the above
  • Perform the test in line with the requirement
  • If substantiated by the above issue test reports

Each of these endorsements / approvals involves independent third party assessment against recognised standards. They give further confidence to Manufacturers, Equipment Users and Regulatory Authorities within the area that we operate by demonstrating our competence, impartiality, performance.

Directorate General of Mines Safety, DGMS

Directorate General of Mines Safety, DGMS in short, is the Regulatory Agency under the Ministry of labour and employment, Government of India in matters pertaining to occupational safety, health and welfare of persons employed in mines (Coal, Metalliferous and oil-mines).

Under the Constitution of India, safety, welfare and health of workers employed in mines are the concern of the Central Government (Entry 55-Union List-Article 246). The objective is regulated by the Mines Act, 1952 and the Rules and Regulations framed there under. These are administered by the Directorate-General of Mines Safety (DGMS), under the Union Ministry of Labour & Employment. Apart from administering the Mines Act and the subordinate legislation there under, DGMS also administers a few other allied legislation, including the Indian Electricity Act.

Under the recently published Approval Policy 2015, Cl No: 6.8, “test reports of a test house accrediated by NABL, may also be accepted subject to confirmation of its ability to conduct tests in pursuance with National / International standards, DGMS Protocol” and the test house in not part of any equipment manufacturers testing facility”

In view of this development, KLPL test report are now accepted by DGMS, in granting product / equipment approval for installations which come under Group I: Coal Mine and Oil Mine application.

KLCS-IECEx Certification Body

KL Certification Services, a division of Karandikar Laboratories Pvt. Ltd., has been accredited as India’s first IECEx Certification Body (ExCB) for the IECEx Certified Equipment Scheme.

Since 2015, when Karandikar Laboratories Pvt. Ltd. became India’s first IECEx Testing Laboratory (ExTL), under the guidance of Baseefa, UK, we have consolidated our expertise and have grown to now become an IECEx ExCB.

In line with our motto “Working for a safer tomorrow” we hope to extend the advantages and convenience of having a local IECEx ExCB to all Local and International manufacturers, in order to conduct the testing and certification activities in timely and cost effective manner.

KLCS has partnered with a number of ATEX Notified Bodies to help Indian manufacturers obtain ATEX Certification. For more details please write to us at sales@karandikarlab.com

Advantages of a local IECEx ExCB & ExTL

IECEx System Objective and its Benefits:

The objective of the IECEx Certified Equipment Scheme is to facilitate international trade in equipment and services for use in explosive atmospheres, while maintaining the required level of safety.

  • Reduced testing and certification
  • Reduced time to market
  • international confidence in the product assessment process
  • one international database listing
  • Maintaining International Confidence in equipment and services covered by IECEx Certification

Process of obtaining IECEx certification

The objective of the IECEx System is to facilitate international trade in equipment and services for use in explosive atmospheres, while maintaining the required level of safety:

On successful application, KLCS will review the design documentation and request the sample configurations for assessment and testing.

KLCS will conduct an audit of the manufacturer’s process and issue a Quality Assurance Report (QAR).

So also, ExTRs can be used to support certification for any IEXEx member body for issuing a IECEx Certificate of Conformity (CofC)

Stator & Rotor Ignition Tests for Ex e and Ex n Motors

In what could be deemed as an important development, Karandikar Laboratories Pvt Ltd, is one of India’s first Test Laboratories to have developed Special Electrical Testing facility for Non-Sparking Ex ‘nA’ and Increased Safety Ex ‘e’ Machines. Our setup is  approved by –

  • IECEx – International Electrotechnical Commission for Explosive Atmospheres
  • NABL – National Accreditation Board for Laboratories
  • BIS – Bureau of Indian Standards
  • PESO – Petroleum & Explosive safety Organization
  • DGMS – Directorate General for Mines Safety

What do the latest standards require?

The latest IEC, EN & IS/IEC standards lay down, construction, test and marking procedures for Rotating Electrical Machines with special emphasis on risk assessment and gas environment tests for rotor and stator designs. Depending on the risk factors identified in the assessment tables, testing may have to be performed separately for rotors and stators. Alternatively, machine could be constructed so as to allow special measures to be employed such as use of space heater, and / or special measures like provision of prestart ventilation/purging.

Keeping in view the above test requirements, KLPL have developed Test Facilities for:

  • Impulse ignition test for stator insulation systems
  • Steady state ignition test for stator insulation systems
  • Gas Tests on Rotors (Conducted at manufacturer’s site)

Benefits to Indian Manufacturers

  • A possible alternative towards performing these tests involves, in the majority of cases, equipping the motor with provision for pre-start ventilation. This means investing in a higher capacity air compressor, piping, and a ventilation control unit. It also requires an additional operation – ventilation – every time the motor is started.
  • Indian Motor Manufacturers can now offer Increased Safety, Ex “e” Machines in line with the latest requirements of IS/IEC standards.

Most importantly, this development would pave the way in ensuring compliance with safety requirements, since testing is the only way to ensure that equipments are really safe.
